It would also help to get the lockdep/lockstat output for those runs
so that more discussion can happen. That framework can be extended to
do all sorts of contention tracking and that is why I took implemented
it in the first place to track the viability of adaptive spins. My

hm. Why is the ticket spinlock patch included in this patchset? It just
skews your performance results unnecessarily. Ticket spinlocks are
independent conceptually, they are already upstream in 2.6.25-rc2 and
-rt will have them automatically once we rebase to .25.

For con
The Real Time patches to the Linux kernel converts the architecture
specific SMP-synchronization primitives commonly referred to as
"spinlocks" to an "RT mutex" implementation that support a priority
inheritance protocol, and priority-ordered wait queues. The RT mutex
implementation allows tasks t
